An Experimental Study of Two-Phase Slug Flow in Hilly Terrain Pipelines

Abstract

Summary Experiments were conducted in a 76.2-mm diameter, 420-m long two-phase flow loop to study slug flow behavior in hilly terrain pipelines. Complex physical phenomena were observed, including generation of pseudoslugs at the horizontal/uphill elbow, variation of slug length along the pipeline, and persistent existence of slug flow in the downhill section.
